(from PS in _dbNavigation.Table1
 join CP in _dbNavigation.Table2 on PS.PropName equals CP.PropName
 where PS.IsDeleted == false && PS.UserName.Equals("REX")

             .Join(_dbNavigation.Table2, t1 => t1.PropName, t2 => t2.PropName, (t1, t2) => new { t1, t2 })
             .Where(x => x.t1.IsDeleted == false && x.t2.UserName == "REX")
